CA2000 is an imported breathing alcohol detector. Compact, accurate and reliable. Its core components using new high-tech micro-changes oxide semiconductor, can accurately detect gas alcohol content, and is not smoke, cola, coffee and other non-alcoholic gases interference. CA2000 compact and lightweight, simple operation, is the best choice for portable applications.Technical parameters:● Press the power switch, the instrument internal self-test and preheating, display a countdown from 200 to 000, which lasted 20 seconds.● countdown to the end of the sound prompts, while the green light is lit, indicates that the instrument properly, you can begin testing.● Align inlet blowing about 5 seconds, if alcohol is detected, the buzzer alarm, red, green flash simultaneously. Another 4 seconds, shows concentration data, if the concentration is between 0.00 and 0.05, only the green light flashes; if greater than equal to 0.05, only the red light flashes, accompanied by rapid audible alarm. Concentration data for 15 seconds after the instrument display turns OFF.● If not detected from blowing alcohol or within 30 seconds after boot without any testing, the instrument displays from 000 turns OFF.● When the instrument displays OFF, you must shut down to re-start the measurement.Precautions● banned from going to blow smoke inside the pores. The liquid can not enter the pores. Do not block the vents● yellow light indicates that the power voltage is low, replace the battery.Used to detect the concentration of alcohol in exhaled air, free from smoke, cola, coffee and other non-alcoholic food tastes interference gases, reliable performance, CA2000 Alcohol Tester compact and lightweight, simple operation, is the best choice for portable applications.Product Features:● Measuring range :0.00-0 .40% (BAC) or 0.00-2.00mg / l (BrAC)● Accuracy: ± 0.01% (0.1% BAC) or ± 0.05mg / l (0.5mg/lBrAC).● Alarm indication: three LCD digital display, audible alarm,● Dimension: 120 × 60 × 25 (mm),● The machine weight: about 200g● Standard configuration: host, 5 mouthpiece, 9V alkaline battery, DC adapter, manual, instrument boxes, portable packageTechnical parameters:● Press the power switch, the instrument internal self-test and preheating, display a countdown from 200 to 000, which lasted 20 seconds.● countdown to the end of the sound prompts, while the green light is lit, indicates that the instrument properly, you can begin testing.● Align inlet blowing about 5 seconds, if alcohol is detected, the buzzer alarm, red, green flash simultaneously.
